Once upon a time net/socket.c:dev_ifsioc() used to handle SIOCSHWTSTAMP and
SIOCSIFMAP. These have different native and compat layout, so the format
conversion had been needed. In 2009 these two cases had been taken out,
turning the rest into a convoluted way to calling sock_do_ioctl(). We copy
compat structure into native one, call sock_do_ioctl() on that and copy
the result back for the in/out ioctls. No layout transformation anywhere,
so we might as well just call sock_do_ioctl() and skip all the headache with
copying.

Only two of dev_ioctl() callers may pass SIOCGIFCONF to it.
Separating that codepath from the rest of dev_ioctl() allows both
to simplify dev_ioctl() itself (all other cases work with struct ifreq *)
*and* seriously simplify the compat side of that beast: all it takes
is passing to inet_gifconf() an extra argument - the size of individual
records (sizeof(struct ifreq) or sizeof(struct compat_ifreq)). With
dev_ifconf() called directly from sock_do_ioctl()/compat_dev_ifconf()
that's easy to arrange.
As the result, compat side of SIOCGIFCONF doesn't need any
allocations, copy_in_user() back and forth, etc.

100GbE Intel Wired LAN Driver Updates 2018-01-24
This series contains updates to fm10k only.
Alex fixes MACVLAN offload for fm10k, where we were not seeing unicast
packets being received because we did not correctly configure the
default VLAN ID for the port and defaulting to 0.
Jake cleans up unnecessary parenthesis in a couple of "if" statements.
Fixed the driver to stop adding VLAN 0 into the VLAN table, since it
would cause the VLAN table to be inconsistent between the PF and VF.
Also fixed an issue where we were assuming that VLAN 1 is enabled when
the default VLAN ID is not set, so resolve by not requesting any filters
for the default_vid if it has not yet been assigned.
Ngai fixes an issue which was generating a dmesg regarding unbale to
kill a particular VLAN ID for the device. This is due to
ndo_vlan_rx_kill_vid() exits with an error and the handler for this ndo
is fm10k_update_vid() which exits prematurely under PF VLAN management.
So to resolve, we must check the VLAN update action type before exiting
fm10k_update_vid(), and act appropriately based on the action type.
Also corrected code comment typos.

Since commit 856dfd69e84f ("fm10k: Fix multicast mode synch issues",
2016-03-03) we've incorrectly assumed that VLAN 1 is enabled when the
default VID is not set.
This occurs because we check the default_vid and if it's zero, start
several loops over the active_vlans bitmask at 1, instead of checking to
ensure that that bit is active.
This happened because of commit d9ff3ee8efe9 ("fm10k: Add support for
VLAN 0 w/o default VLAN", 2014-08-07) which mistakenly assumed that we
should send requests for MAC and VLAN filters with VLAN 0 when the
default_vid isn't set.
However, the switch generally considers this an invalid configuration,
so the only time we'd have a default_vid of 0 is when the switch is
down.
Instead, lets just not request any filters for the default_vid if it's
not yet been assigned.

Currently, when the driver loads, it sends a request to add VLAN 0 to the
VLAN table. For the PF, this is honored, and VLAN 0 is indeed set. For
the VF, this request is silently converted into a request for the
default VLAN as defined by either the switch vid or the PF vid.
This results in the odd behavior that the VLAN table doesn't appear
consistent between the PF and the VF.
Furthermore, setting a MAC filter with VLAN 0 is generally considered an
invalid configuration by the switch, and since commit 856dfd69e84f
("fm10k: Fix multicast mode synch issues", 2016-03-03) we've had code
which prevents us from ever sending such a request.
Since there's not really a good reason to keep VLAN 0 in the VLAN table,
stop requesting it in fm10k_restore_rx_state().
This might seem to indicate that we would no longer properly configure
the MAC and VLAN tables for the default vid. However, due to the way
that fm10k_find_next_vlan() behaves, it will always return the
default_vid as enabled.

When a VF is under PF VLAN assignment:
ip link set <pf> vf <#> vlan <vid>
This will remove all previous entries in the VLAN table including those
generated by VLAN interfaces created on the VF. The issue arises when
the VF is under PF VLAN assignment and one or more of these VLAN
interfaces of the VF are deleted. When deleting these VLAN interfaces,
the following message will be generated in "dmesg":
failed to kill vid 0081/<vid> for device <vf>
This is due to the fact that "ndo_vlan_rx_kill_vid" exits with an error.
The handler for this ndo is "fm10k_update_vid". Any calls to this
function while under PF VLAN management will exit prematurely and, thus,
it will generate the failure message.
Additionally, since "fm10k_update_vid" exits prematurely, none of the
VLAN update is performed. So, even though the actual VLAN interfaces of
the VF will be deleted, the active_vlans bitmask is not cleared. When
the VF is no longer under PF VLAN assignment, the driver mistakenly
restores the previous entries of the VLAN table based on an
unsynchronized list of active VLANs.
The solution to this issue involves checking the VLAN update action type
before exiting "fm10k_update_vid". If the VLAN update action type is to
"add", this action will not be permitted while the VF is under PF VLAN
assignment and the VLAN update is abandoned like before.
However, if the VLAN update action type is to "kill", then we need to
also clear the active_vlans bitmask. However, we don't need to actually
queue any messages to the PF, because the MAC and VLAN tables have
already been cleared, and the PF would silently ignore these requests
anyways.

The fm10k driver didn't work correctly when macvlan offload was enabled.
Specifically what would occur is that we would see no unicast packets being
received. This was traced down to us not correctly configuring the default
VLAN ID for the port and defaulting to 0.
To correct this we either use the default ID provided by the switch or
simply use 1. With that we are able to pass and receive traffic without any
issues.
In addition we were not repopulating the filter table following a reset. To
correct that I have added a bit of code to fm10k_restore_rx_state that will
repopulate the Rx filter configuration for the macvlan interfaces.

net: sched: propagate extack to cls offloads on destroy and only with skip_sw
This series some of Jiri's comments and the fact that today drivers
may produce extack even if there is no skip_sw flag (meaning the
driver failure is not really a problem), and warning messages will
only confuse the users.
First patch propagates extack to destroy as requested by Jiri, extack
is then propagated to the driver callback for each classifier. I chose
not to provide the extack on error paths. As a rule of thumb it seems
best to keep the extack of the condition which caused the error. E.g.
err = this_will_fail(arg, extack);
if (err) {
undo_things(arg, NULL /* don't pass extack */);
return err;
}
Note that NL_SET_ERR_MSG() will ignore the message if extack is NULL.
I was pondering whether we should make NL_SET_ERR_MSG() refuse to
overwrite the msg, but there seem to be cases in the tree where extack
is set like this:
err = this_will_fail(arg, extack);
if (err) {
undo_things(arg, NULL /* don't pass extack */);
NL_SET_ERR_MSG(extack, "extack is set after undo call :/");
return err;
}
I think not passing extack to undo calls is reasonable.

Problem description:
After ethernet cable connect and disconnect for several iterations on a
device with i210, tx timestamp will stop being put into the socket.
Steps to reproduce:
1. Setup a device with i210 and wire it to a 802.1AS capable switch (
Extreme Networks Summit x440 is used in our case)
2. Have the gptp daemon running on the device and make sure it is synced
with the switch
3. Have the switch disable and enable the port, wait for the device gets
resynced with the switch
4. Iterates step 3 until the device is not albe to get resynced
5. Review the log in dmesg and you will see warning message "igb : clearing
Tx timestamp hang"
Root cause:
If ptp_tx_work() gets scheduled just before the port gets disabled, a LINK
DOWN event will be processed before ptp_tx_work(), which may cause timeout
in ptp_tx_work(). In the timeout logic, the TSYNCTXCTL's TXTT bit (Transmit
timestamp valid bit) is not cleared, causing no new timestamp loaded to
TXSTMP register. Consequently therefore, no new interrupt is triggerred by
TSICR.TXTS bit and no more Tx timestamp send to the socket.

Before libvirt modifies the MAC address and vlan tag for an SRIOV VF
for use by a virtual machine (either using vfio device assignment or
macvtap passthru mode), it saves the current MAC address and vlan tag
so that it can reset them to their original value when the guest is
done. Libvirt can't leave the VF MAC set to the value used by the
now-defunct guest since it may be started again later using a
different VF, but it certainly shouldn't just pick any random value,
either. So it saves the state of everything prior to using the VF, and
resets it to that.
The igb driver initializes the MAC addresses of all VFs to
00:00:00:00:00:00, and reports that when asked (via an RTM_GETLINK
netlink message, also visible in the list of VFs in the output of "ip
link show"). But when libvirt attempts to restore the MAC address back
to 00:00:00:00:00:00 (using an RTM_SETLINK netlink message) the kernel
responds with "Invalid argument".
Forbidding a reset back to the original value leaves the VF MAC at the
value set for the now-defunct virtual machine. Especially on a system
with NetworkManager enabled, this has very bad consequences, since
NetworkManager forces all interfacess to be IFF_UP all the time - if
the same virtual machine is restarted using a different VF (or even on
a different host), there will be multiple interfaces watching for
traffic with the same MAC address.
To allow libvirt to revert to the original state, we need a way to
remove the administrative set MAC on a VF, to allow normal host
operation again, and to reset/overwrite the VF MAC via VF netdev.
This patch implements the outlined scenario by allowing to set the
VF MAC to 00:00:00:00:00:00 via RTM_SETLINK on the PF.
igb_ndo_set_vf_mac resets the IGB_VF_FLAG_PF_SET_MAC flag to 0,
so it's possible to reset the VF MAC back to the original value via
the VF netdev.
Note: Recent patches to libvirt allow for a workaround if the NIC
isn't capable of resetting the administrative MAC back to all 0, but
in theory the NIC should allow resetting the MAC in the first place.
